[1.19.4] How to disable specific biomes from generating (and other small tweaks)?

[SoLegendary]

I want to disable the generation of specific biomes on new world creation. I also want to tweak some other world generation features of specific other biomes (eg. changing density of trees in a forest, density of surface ores on a mountain, etc.)

I see lots of options for creating new custom biomes with datapacks (eg. using https://misode.github.io/worldgen/biome/), I don't know how to modify existing biomes or remove them entirely.

Is there a way to do it in the Java code or are data packs the best way? Is there a guide someone can provide for it?

I would use a datapack. Additionally, I would suggest creating a world preset instead since you are basically making your own world configuration.
